RE: Data flow testing
The data flow testing selects test paths of a program according to the locations of definitions and uses of variables in the program.To illustrate the data flow testing approach,assume that each statement in a program is assigned a unique statement number and that each function does not modify its parameter or global variables.

RE: Data Validation testing
Data flow means the transfer of data from one GUI to another in an application
under test. it is associated with both black box(functionality check) and white box testing. an example would be, in a web page the click of a button links to another window( which is data flow). The subsequent transfer/display of related datas in the new window due the action of the previous window is termed as data transfer.
